Es wird eine Befestigungsvorrichtung angegeben, die Folgendes umfasst: einen Einführungsbereich (51) für eine Kapillare (20), die einen Sensorbereich (11) eines Lichtwellenleiters (10) zumindest bereichsweise umgibt, wobei die Kapillare (20) einen Befestigungsbereich (21) umfasst, der beabstandet von dem Sensorbereich (11) des Lichtwellenleiters (10) anordenbar ist; einen Detektor (52), der dazu konfiguriert ist, eine Markierung (22) an der Kapillare (20) zu detektieren, die an der Kapillare (20) bereitgestellt ist, um den Befestigungsbereich (21) der Kapillare (20) anzuzeigen; und einen Erwärmungsbereich (53), der dazu konfiguriert ist, den Befestigungsbereich (21) der Kapillare (20) zu erwärmen, vorzugsweise automatisch für eine vorbestimmte Zeitdauer zu erwärmen, wenn der Detektor (52) die Markierung (22) detektiert.Die Befestigungsvorrichtung ist verwendbar zum Durchführen eines Befestigungsverfahrens. The invention relates to a securing method, comprising the following Steps: providing an optical waveguide made of a material with a first melting temperature, wherein a sensor region of the optical waveguide has at least one integrated temperature sensor element; providing a capillary made of a material with a second melting temperature, in such a way that the capillary surrounds at least regions of the sensor region of the optical waveguide, and that a securing region of the capillary is arranged at a distance from the sensor region, wherein the second melting temperature is lower than the first melting temperature, wherein the temperature sensor element is arranged in an end region of the optical waveguide, and the end region is inserted into the capillary; securing the securing region of the capillary to the optical waveguide, involving a heating of the securing region of the capillary to a heating temperature that is equal to or higher than the second melting temperature; and heating the free end of the capillary to a heating temperature that is equal to or higher than the second melting temperature. A temperature sensor comprising an optical waveguide with at least one integrated temperature sensor element can be obtained with the method. A securing device comprises an Insertion region for the capillary, a detector and a heating region. The securing device can be used for carrying out the method.
